In what might have been her final race, Successful Song was the dominating winner of the $300,000 Florida Sunshine Millions Distaff Stakes on Saturday at Gulfstream Park.

Successful Song, a 6-year-old, took the lead entering the final turn and went on to beat Speak Easy Gal by 3 1/2 lengths in the 1 1/8 mile turf stakes for Florida bred fillies and mares 4 years old and up.

Owner Live Oak Plantation in Ocala went into the race with a plan for it to be the last for Successful Song before retiring her to be a broodmare, said her trainer Eddie Plesa Jr.

“I’ll tell them that she’s looking as good as ever,” Plesa said, adding that Live Oak Plantation officials will decide whether to bring her back to racing.

Successful Song, the 6-5 favorite, was ridden by Joel Rosario and won in 1:52.28 on a track listed as sloppy following Saturday morning’s rain.

The win was Successful Song’s eighth in 27 career starts, including five stakes victories.

On its Florida Sunshine Millions Day, Gulfstream had four other stakes races — all with $150,000 purses for Florida-breds.

• Off the Jak, at 13-1, won the Sprint by three quarters of a length over Bahamian Squall. He ran six furlongs in 1:10.27 under jockey Jose Alvarez.

• Teaks North, at 8-1, led the entire route and beat 1-2 favorite Doubles Partner by 2 1/2 lengths in the Turf Stakes for males at 1 1/8 miles.

• Regalo Mia won the Filly and Mares Turf, at 1 1/8 miles, by three-quarters of a length over Hooh Why.

• Golden Mystery coasted to a 5 1/4 length win over Emma’s Encore in the Filly and Mares Sprint at six furlongs.
